Japan in
October.

Day, night and rain figures are the measured October normals from each place’s qualifying NOAA station. Open a place for that month’s full answer.

Read these as long-term planning evidence, not a forecast. Compare daytime and overnight temperature together, then use rainfall and wet-day frequency to judge how often outdoor plans may need flexibility. Mountain, coastal and island conditions can differ sharply over short distances, so the linked place page and its station distance matter more than the country average. Before booking, check current local forecasts, seasonal closures, daylight, transport and any weather warnings. Data collection uses the 1991–2020 station-normal period; the published evidence was rechecked on 3 September 2026.

Use the table to shortlist places, then open each place page to compare the reporting station, distance and all twelve months. A small country table can contain only a few qualifying stations; that is a coverage limit, not evidence that other places share the same conditions.
